Solution:

Given

Alok bought 30 kg rice price at = Rs. 8.50 per kg

Alok bought 20 kg rice price at = Rs. 8 per kg

Calculation

Cost price 30 kg = 30 × 8.50

⇒ Rs. 255

Cost price 30 kg = 20 × 8

⇒ Rs. 160

Cost price of mixture is = 255 + 160

⇒ Rs. 415

Total bought rice is = 30 + 20

⇒ 50 kg

Mixture per kg price is = 415/50

⇒ Rs. 8.30

∴ S.P. of the mixture per kg= (8.30/83) × 100

⇒ Rs. 10

Where x is the C.P. of the mix. per kg.

or, 25.50 - 3x = 2x - 16

or, 5x = 25.50 + 16

∴ Rs. 8.30

∴ S.P. of mix. per kg at 20% profit

= Rs. 10.00
